<p class="answer__detail">functions Login, SetCredentials, etc. are methods of the <b>AuthenticationService service</b> . <br>
A factory is a way to define a service. The only difference between .service and .factory is that in the first case you put in an object constructor, and in the second - a factory function that will figure out how to create an object.<br><pre><code class="hljs">// вот сервис
function MyService (dep1, dep2) {
this.dep1 = dep1;
this.dep2 = dep2;
}
// А вот фабрика этого сервиса
function myServiceFactory(dep1, dep2) {
return new MyService(dep1, dep2);
}
// в результате в контейнере зависимостей будет крутиться
// 2 инстанса одного и того же сервиса. То есть одинаковый результат
// при двух подходах.
module.service('foo', MyService)
module.factory('bar', myServiceFactory);</code></pre><br>
In your example, the factory is used banally because you need to make an object somewhere and for this you use a "module". Well, they say for encapsulation, etc. In order not to expose the dependencies of your object to anyone. Well, Object.create is just for the faint of heart.</p>
